(El. 145-4) This invention relates to improvementsin planes and more particularly relates to an improved form of electrichand plane adapted for edge and surface planing.

A principal object of the present invention is to provide an improvedform of electric hand plane arranged with a view toward utmostsimplicity in construction and operation and economy in manufacture.

Another object of the invention is to provide an improved form ofelectric hand plane utilizing an adjustable wedge for varying the depthof the planing cut and having a simplified means for adjusting andholding the wedge in place.

A still further object of the invention is to improve upon the electrichand planes heretofore in use by spacing the motor from the cutter blockand cutter blades and above the bottom surface of the plane, to provideclearance for surface planing and by so forming the cover for the cutterblades as to effect the discharge of chips to one side of and downwardlyof the plane, by the impelling action of rotation of the cutter blockand blades.

A still further object of the invention is to provide a simplifiedmounting for the cutter block of an electric hand plane, driven from amotor shaft spaced from the axis of rotation of the cutter block, inwhich an improved mounting for the cutter block is provided utilizingbronze bearings and distributing the loads between the ends and insidesof the bearings at opposite end portions of the cutter block.

Still another object of the invention is to provide a simple andimproved form of cutter block for an electric hand plane in which thecutter block is driven from a spaced motor shaft through a cogged beltand toothed pulleys, and in which one toothed pulley is formed integrally with the cutter block.

Still another object of the invention is to provide a simplified andimproved mounting for the cutter block of an electric hand plane whereinthe cutter block is mounted between the side walls of the base shoe ofthe plane on sleeve bearings on a stationary hollow shaft and whereinthe hollow shaft is cross-drilled intermediate its ends to form asimplified form of means for lubricating the bronze bearings.

A still further object of the invention is to improve upon the mountingof the cutter blades on the cutter block of an electric hand plane inwhich the cutter blades extend chordally of an are subscribed by therotating blades, and in which bolts having heads with squared shanksregistering with elongated slots in the blades forms a means forretaining the blades to the cutter block and accommodating adjustment tothe blades with respect to the block.

These and other objects of the invention will appear from time to timeas the following specification proceeds and with reference to theaccompanying drawings wherein:

FIGURE 7 is a perspective view of one of the cutter blades; and

FIGURE 8 is an exploded View of the cutter block and blades.

In the embodiment of the invention illustrated in the drawings, I haveshown in FIGURE 1 an electric hand plane 10 in position to plane theedge of a board and guided to plane in the proper plane by a guide plateor fence 11, adjustable about pins 12, 12 extending longitudinally ofthe plane, to accommodate the plane to edge a board square with thesurface of the board or at any desired bevel with respect to the board.The pivot pins 12, 12 are mounted on brackets 13, 13 detachably mountedon a side wall 14 of a base shoe 15 of the plane, by machine screws 16,16. Each bracket 13 extends outwardly and downwardly of the base shoe 15in an arcuate path subscribed from an axis coaxial with the axis of theassociated pivot pin 12 and has a slot 17 therein, formed about the axisof the pin 12 and having a screw 18- slidably extending therethrough.The screw 18 extends through a similar slot in a bracket 19 secured tothe outer face of the fence 11 and has a wing nut 20 threaded thereon tohold the fence 11 in the proper position of adjustment.

The base shoe 15 may be made from cast aluminum and includes a planehorizontal bottom surface 21 extending for a greater portion of thelength thereof, and terminating at its forward end in a gap 22 providedin the base shoe 15 for the blades of a rotary cutter block 23 havingoppositely facing blades 24 carried thereby and rotatably driven toeffect a planing operation.

The base shoe 15 also has a bottom inclined plane surface 25 (FIGURE 4)extending upwardly from the gap 22 to the forward end of the base shoeand forming an inclined plane surface abutted by a correspondinginclined plane surface 26 of an adjustment wedge 27. The wedge 27 isgenerally triangular in form and has a flat or horizontal bottom 29adjustable to vary the depth of the planing cut by movement of theinclined surface 26 along the inclined surface 25 toward and from thegap 22. The inclined surface 26 of the wedge 27 has guide grooves 30extending along opposite sides thereof, slidably engaged bycorresponding ribs forming the outer margins of a recessed portion 31 ofthe inclined surface 25 of the base shoe 15.

The triangular wedge 27 may be an aluminum casting and has a recessedtop portion 32 having a central boss 33 extending upwardly therefrominto abutting engagement with the recessed portion 31 of the inclinedsurface 25 of the base shoe 15. The inclined plane surface 25 of thebase shoe 15 has a slot 35 extending therealong in registry with theboss 33. A machine screw 36 extending through a washer 37 and the slot35 and is threaded in the boss 33 to retain the traingular wedge 27 inposition.

In FIGURE 4, the triangular wedge 27 is shown in an extreme position, toposition the cutter blades 24 to make a maximum depth cut while inFIGURES 1 and 5, the triangular wedge 27 has been retracted to effectthe taking of a fine or shallow cut. Suitable indicia (not shown) may beprovided on the 'side wall of the shoe 15 and the triangular wedge 27 toindicate the depth of cut for the position of adjustment of said wedge.A simplified adjustment for adjusting the depth of cut of the plane has,therefore, been provided operable merely by the turning of a machinescrew holding the triangular wedge to the base shoe of the plane invarious selected positions of adjustment in accordance with the desiredsetting of the cutting depth of the planer blades.

The base shoe also has an upstanding central boss 39 at its forward endinto which is threaded an upwardly projecting handle grip 40 for theplane.

The base shoe forms a mounting for a motor 41 extending thereacross andto one side of said base shoe. The mounting of the motor 40 on the baseshoe 15 spaces the motor casing above said base shoe a distancesuflicient to provide sufficient clearance below the motor casing, topermit surface planing when the fence 11 is removed from the base shoe.The motor has a hollow split handle 43 extending upwardly and rearwardlytherefrom.

The handle 43 is shown as being in the form of an annular sector of acircle and as being connected to the motor casing by radial spokes orribs 44. The split handle has a hollow interior portion 45 for thestarter switch (not shown) for the motor. The starter switch is operatedby a trigger 46 in a convenient location to be gripped by the fingers,while holding the plane for planing. The switch within the handle may bea type of safety switch in which the motor 41 is de-energized whenpressure is relieved from the trigger 46, and commonly called a dead mansafety switch.

The motor 41 may be a conventional form of high speed electric motor andhas a toothed motor pinion or pulley 4-7 meshing with and driving acogged belt 50, commonly known as a timer belt. The cogged belt 50 inturn meshes with and drives a toothed pulley 51 coaxial with and shownin FIGURE 3 as being formed integrally with the cutter block 23. Apositive nonslipping drive is thus provided from the motor to the cutterblock for driving said cutter block at a sutficiently high speed toeffect eflicient planing, the speed of rotation of said cutter blockbeing in the order of 14,000 rpm.

Referring now to FIGURE 3 and the mounting of the cutter block 23 in thegap 22 between side walls 53 and 54 of the base shoe 15, the cutterblock 23 has a central bore or drilled portion 55 having flanged sleevebearings 56 extending therein from opposite ends thereof. The flangedportions of the sleeve bearings 56 are engaged by annular ribs 57extending outwardly of opposite sides of the cutter block 23. Saidsleeve bearings are mounted on a hollow shaft 59 extending through thebore 55 and mounted at its ends in boss portions 52 formed integrallywith the side walls 53 and 54. The hollow shaft 53 has a central drilledportion 63 leading downwardly of said shaft into the space between thesleeve bearings 56. A set screw 60 threaded in a top wall portion 61 ofa downwardly opening recessed portion 62 of the boss 52 formedintegrally with the wall 53 engages a drilled portion 58 of the shaft 59and locates. the drilled hole 63 in the center of said hollow shaft tolead downwardly between the bearings 56. The drilled hole 63 thus formsan oil hole to conduct oil placed into the hollow shaft 59 from eitherend thereof to the central portion of the block 23 between the sleevebearings 56 to oil said bearings by the oil in the interior of thecutter block 23 and flowing to opposite ends thereof. Washers 65 areplaced on the hollow shaft 59 between the flanges of the flanged bearingsleeves 56 and the insides of the walls 53 and 54, to space the cutterblock 23 midway between the walls 53 and 54 and to take up end thrust onsaid cutter block. Opposite ends of the hollow shaft 59 are closed byend caps 66, 66 which may be snapped thereon and removed to accommodateoiling of the bearings 56 for the cutter block.

The cutter block 23 has opposite parallel plane surfaces 67 spaced equaldistances from the axis of rotation of said cutter block, and extendingchordally of the arc of rotation of said cutter block, and formingabutment surfaces for the cutter blades 24. Spaced bolt holes 69elongated in cross-section lead from the plane surfaces 67 through thecutter block and open into recessed portions 70 of the cutter block andaccommodate adjustment of the cutter blades 24 with respect to thecutter block. The recessed portions 70- have abutment surfaces 71parallel to the surfaces 67, and shown in FIG- URE 8 as extendingdiametrically of the axis of rotation of said cutter block. The abutmentsurfaces 71 are abutted by nuts 72 threaded on bolts 73 retaining thecutter blades 24 to the plane surfaces 67 of the cutter block 23.

As shown in FIGURES 7 and 8, the cutter blades 24 have spacedrectangular holes 74 leading therethrough to be engaged by squared shankportions 75a of the bolts 73, herein shown as being carriage bolts. Thesquared shank portion 75a of the bolts 73 snugly fit in the rectangularholes 74, and the squared shanks are of sufficient length that they bearagainst the plane faces 67 when tightened. This prevents shifting of thecutter blades and relieves the cutter blades from tightening forces. Thebolt holes 69, 69, however, form a means to accommodate adjustment ofthe cutter blades 24 with respect to the cutter block 23.

The cutter blades 24 may be stamped from cold roll steel and may then beground and case hardened and honed. A suitable material providing longlife for the blades is #1018 c.r.s.

The base shoe part defining the rear wall of the gap 22 between thehorizontal plane surface 21 and the forwardly spaced inclined surface 25of the base shoe part conforms to the arc of rotation of the cuttingedges of the cutter blades 24 and is spaced radially outwardlytherefrom, as indicated by reference character 75. A forward wall 76 ofthe gap 22 extends upwardly of the inclined surface 25, and is inclinedin a forward direction as it extends upwardly of said inclined surface,to provide sufficient clearance to accomodate the cuttings or shavingsto be impelled by the cutter blades 24 to and out one end of a chipejector passageway 77 formed on the underside of a cover 79 for thecutter block 23 and cogged belt 50. The side wall 53 extending acrossthe gap 22 has a chip ejector recess 80 formed therein cooperating withthe passageway 77 to accommodate the ejection of chips to one side ofand downwardly of the base shoe 15.

The cover 79 has an elonated side guard portion 81, conforming generallyto the form of the cogged belt 50, motor pulley 47 and toothed pulley51, to guard said cogged belt and pulley, and is secured to one end ofthe motor 41 as by a machine screw 83. The cutter block cover 79 alsohas a cutter guard portion extending partially around the cutter block23 and cutter blades 24 and terminating into a chip ejector portionhaving the chip ejector passageway 77 extending along the insidethereof. The chip ejector portion 85 has spaced ears 86 extendingforwardly therefrom abutting the top surfaces of bosses 87 formedintegrally with the base shoe 15 and extending upwardly therefrom andsecured thereto as by machine screws 88. The interior of the cutterguard 79 has an interior wall 90 forming a continuation of the wall 75and terminating at its advance end into an upright wall interior portion91 of the chip ejector cover 85. The interior wall portion 91 forms arear wall of the chip passageway 77. The wall 91 diverges from an endwall 92 of the chip passageway 77 and wall 54 thereof, with respect tothe upright wall 76, to form a chip passageway of increasingcross-sectional area from the closed end to the discharge end of thechip ejector cover 85. The chip ejector cover 85 extends to one side ofthe wall 53 and has a downwardly turned discharge end 95 spacedoutwardly of the wall 53 and discharging the cuttings to one side of thebase shoe 15 and downwardly toward the ground.

The chip ejector cover 85 and converging passageway 77 extending alongthe interior of said cover thus effect the ejection of the chips beyondand to one side of the base shoe 15 by the impelling action of thecutter blades 24 and cutter block 23, in a simple and effective mannerwithout the use of the usual blowers or suction devices.

While I have herein shown and described one form in which my inventionmay be embodied, .it may readily be understood that various variationsand modifications in the invention may be attained without departingfrom the spirit and scope of the novel concepts thereof as defined bythe claims appended hereto.
